SUSPENSION METAL-SHAPER.

SPECIFICATION forming part @freezers Appleman met August 5, 139s.

Be it known that I, HENRY J. HENDEY, a citizen of the United States, residing at Torrington,in the county of Litchfield and State of Connecticut, have invented certain new and useful `Improvements in Suspension Metal- Shapers ;vv and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same.

My invention has for its object to simplify and improve the construction of metal shapers, the special object being to provide a conand adapted to receive very large and long pieces of work, to receive in fact any shaped With these ends in view I have devised a novel form of machine which is all open under the cross head, the saddle being suspended from the cross head and the cutter bar ,suspended in the saddle. It should be understood however that my novel improvements are not restricted in their application to large sized machines, as I make smaller sized machines upon the same principle and find my novel improvements in the details'of construction to work admirably in such smaller sized machines.

In the accompanying drawings forming part of this'speciiication Figure 1 is a side elevation of the machine complete a portion of the girder being broken away to show the operation of the mechanism for raising and lowering the cross head; Fig. 2 an end elevation as seen from the right in Fig. 1; Fig. 2a a detail sectional viewon an enlarged scale corresponding with Figs. 1 and 2, the line being indicated by' v fu in Fig. 1; Fig. 3 a horizontal section on the line :raz in Fig. the cross head being partially broken away to show the saddle; Fig. 4:' an end elevation of the cross head detached; Fig. 5 a vertical longitudinal section on the line y y in Fig. 8 looking toward the right, the same line also appearing in Fig. 3; Fig. 6 a'vertical transverse section on the line z ,c in Figs. 3 and 5 looking toward the left; Fig.'7 a plan view of the top of the machine, a portion ofV the reversing mechanism appearing 'in section; Fig. 8 a vertical trans- Patent No. 517,612, dated April e, 1894.

verse section on the line s s in Figs-1 and 3 looking toward the left; Fig. 9 (see Sheet 3) a detail sectional view on an enlarged scale of parts appearing inFig'. 1, the position of the parts being changed.

1 denotes the bed, 2 the housings or uprights, 3 the girder, A the cross head, B the saddle, and C the cutter bar. sential movements of the machine are a Vertical reciprocatory movement of the cross head carrying the saddle and cutter bar, a horizontal reciprocatory movement of the saddle carrying the cutter bar, 'and a horizontal reciprocatory movement of the cutter b ar at right angles to the line of movement of the saddle. The Vcross head is provided with vertical tongues 4, see Fig. 3, which engagecorresponding grooves in the inner faces of the housings. The cross head is additionally secured in place by bolts 5 which pass through the ends of the cross head and move in vertical slots 6 in the housings, see Fig. 5. The vertical movement of the cross head by which it is adjusted in use is imparted by means of screws 7 the lower ends of which engage the cross head, see Fig. 8, and which pass through worm wheels 8 which are internally threaded to receive them and which are themselves engaged by worms 9 on a shaft 10 journaledin brackets 11. VAt the mid-length of shaft 10 are two bevel gears 12 which face each other. These gears are loose on the shaft, are held against outward movement by collars 13 and are provided on their inner faces with clutch members 14. Both of these bevel gears engage a bevel gear '15 on a shaft 16, to which power is applied by a belt running over a pulley 17. Between bevel gears 12 is a slidingclutch member 18 which is keyed to the shaft so as rotate therewith and is adapted to engage either of the clutch members 14, said' sliding clutch member being controlled by a hand lever 19, see Fig. 7. In the drawings, sliding clutch member 18 is shown as disengaged from both clutch members which is its normal position,

The three esshaft 10 being stationary except while the IOC 8, and that movement of the hand lever in the opposite direction will cause the shaft to rotate in the opposite direction and will lower the cross head.

Power to move the saddle and cutter bar is received from belts running over belt pulleys both of which are loose on a shaft 21. One of these belt pulleys is provided with two diameters so that if desired the speed may be changed. As one of the belts is crossed, see dotted lines Fig. 1, it will be apparent that belt pulleys 2O will rotate in opposite directions. Between belt pulleys 20 and adapted to engage the inner periphery of either of them is a sliding friction clutch wheel 22 which is controlled by means of a sliding rod 23 within shaft 2l, the sliding clutch Wheel being connected to the rod by means of a pin 24 which passes through a slot 25 in the shaft. Rod 23 is moved in or out to reverse the movement of shaft 21 by a forked arm 26 which engages said rod between collars 27 and is carried by a rock shaft 28which is itself supported by a bracket 29 on the girder in which it slides freely as the cross head moves up or down, and by a bracket 30 on the cross head. At the lower end of rock shaft 28 is a bevel segment gear 3l which engages a bevel segment gear 32 on a horizontal rock shaft 33 journaled in suitable brackets upon the saddle, one end in the present instance being journaled in bracket 30.

34 denotes a hand lever on shaft which is -keyed thereto so as to oseillate said shaft when it is moved, but which is free to slide longitudinally thereon as the saddle moves forward or backward on the cross head.

36 denotes a bell crank lever the arms of which are separated and the shank of which is journaled in a bracket 37 on the saddle, see Fig. 1.

denotes a rod which connects one arm of the bell crank lever with hand lever 34, see Fig. 2 in connection with Fig. 1. The lower armof the bell crank lever which I have denoted specifically by 36a lies in a position to be engaged by adjustable dogs 38 on a rod 39 one end of which is secured to a bracket 40 at the forward end of the cutter bar, the rear end thereof being free to slide in a guide 41 on the saddle, see Fig. 3. It will be seen therefore y that the forward and backward movements of the saddle are controlled automatically by the engagement of `dogs 38 with arm 36 of the bell crank lever, said dogs being capable of adjustment in the usual manner to produce a long or short stroke, and that if desired the movement of the saddle may be reversed `at any time by manipulation of hand lever 34.

Rock shaft 28 and sliding rod 23 are locked at either eXtreme of their movement by means of a spring latch 42, see Fig. 7, in connection with'Figs 1 and 2. This latch is secured to the cross head and is provided with a double incline 43 which is engaged by a corresponding double incline on an arm 44, see Figs. 1

and 7, which extends outward from rock shaft 28. The engagement of these inclines acts to hold the rock shaft and with it of course the sliding rod at either of its extremes of move ment so that sliding friction clutch wheel 22 is held in engagement with either of the belt pulleys on shaft 21 until it is thrown out of engagement and into engagement with the other belt pulley. When rock' shaft 28 is oscillated arm 44 will pass the double incline on the latch and the other faces of the inclines will be in engagement.

The reciprocatory movement of the saddle on the cross head is produced by means of a non-rotating screw 45 the opposite ends of which are rigidly secured to the cross head, see Fig. 3. This screw is engaged by a feed nut 46, see Figs. 3 and 5, through which the screw passes. This nut passes through a boss 47 on the saddle, see Fig. 3, its inner end consisting of a collar 48 which lies partially in a groove 49 in the top of the saddle. The outer end of feed nut 46 is provided with worm teeth adapted to engage a worm 50 on a shaft 51 journaled in suitable bracketson the saddie, see Fig. 5. The saddle is secured to the cross head by plates 52 which engage flanges 53 on the cross head and are rigidly bolted to the saddle. These plates hold the saddle firmly in place but leave it free to slide upon the cross head. The construction and operation of these parts Will be clearly understood from Figs. 3, 5 and 6. At the opposite end of shaft 51 is a pinion 54. Intermittent motion is imparted to this pinion to turn the feed nut and thereby move the saddle on the cross head,in the manner which lwill now describe. Turning to Figs. 2 and 7, at the opposite end of shaft 21 from sliding rod 23 is a bevel pinion 55 which engagesa bevel gear 56 on a vertical shaft 57 the upper end of which is journaled in a bracket 58 upon the girder, and in a bracket 59 upon the saddle. Keyed to this shaft so as to slide freely thereon longitudinally is a bevel pinion 60 which meshes with a bevel gear 61 on a shaft 62 journaled in brackets 63 depending from the cross head, one of said brackets specifically denoted by 63n being detachable. This shat'tis provided with aspline 64 which engages and carries a sliding pinion 65, see Fig. 5 the function of which is to drive the cutter bar, as will presently be more fully explained, and also sliding sleeves 66 which are journaled in the saddle, see Fig. 3, and a sliding bevel pinion 67which engages a bevel pinion 68 on a shaft 69 journaled in brackets 70 upon the saddle. At the opposite end of shaft 69 is a pinion 71 which engages a gear wheel 72 journaled on a hub 73 which projects outward from the saddle, see Fig. 9, in connection with Fig. 1. 74 denotes a rocker also journaled on hub 73.

75 denotes leather Washers and 76 a metallic disk against which a nut 77 bears, said nut being in use tightened up sufficiently to cause the gear wheel to carry the rocker forward until a pin 78 on the rocker engages either of the IOO IIO

, ipins -79 which extend outward'from thesa'dl Y 517,612 e 3 dle. When the' pin on the rocker engages one of the pins 79 the rocker is held thereby Auntil the`reverse movement takes place, gear wheel 72ycontinuing to move forward` and slippingppast therocker.

80 denotes aconnecting rod which is-adjustably secured to-the rocker in the usual manner to permit the feed at eachactuation to be increased or diminished. The opposite end of the connecting rod is pivoted to a lever 81 journaled on a sleeve 82 extending outward from a gear wheel 83 itself` journaled on a hub 84 extending outward from the saddle, see Fig. 2a in connection with Figs. 1 and 2. ',At the opposite end of lever 81 is a spring pawl 85 which -is adapted to engage a double faced ratchet 86'on the face of gear wheel 83. This pawl is made Vreversible to'provide for feeding in eitherdirection, and suitable means is providedv for locking it out of operative position. Y l

-87 isa hand wheel keyed to the outer end of sleeve 82. 1t will be apparent that each forward and backward movement of the connecting rod will oscillate leverv 81 and by v means of the spring pawl engagingthe ratchet will move gear'wheel 83 whichmeshes with pinion 54 and which in turn by means of worm'50 and lfeed nut 46 imparts movement in one direction or-the other to the saddle. It will be obvious to those familiar with the art that each forward and backward movement of the cutter bar by means of adjustable dogs 38 and intermediate mechanism already'fully described Willreverse the movement of gear wheel 72 and the rocker which in turn produces a forward movement of gear wheel 83 and also a backward movement of lever 81, the spring pawl slipping over the teeth of the ratchet during the back- Ward movement. By means of hand `wheel 87 the operator is enabled to turn feed nut 46 and to place the saddle in any required position, notably when commencing pieces of work. In order to cause the saddle to be fed in the opposite direction after it has traversed the piece of metal being operated upon in one direction, it is simply necessary for the operator to lift spring pawl 85 out of engagement with the double faced ratchet, give it a half turn and letit drop back to place, it being of course understood that the back of the pawl is beveled in the usual manner so that when lever 81 is moved in one direction the bevel upon the back of the pawl will cause it to slip backward over the teeth of the double faced ratchet and when the lever is moved in the opposite direction the pawl will carry the ratchet forward. The reciprocatory `Inovement of the cutter bar is imparted by sliding pinion which engages a rack 88 forming' part of the cutter bar, see Figs. 5 and 8. At

the outer end of the cutter bar is theusual tool carrier S9 shown as carrying a tool 90.

91 is the usual adjusting screw for raising or lowering the tool carrier and tool.
